It's obvious when your air conditioner isn't working well. Your home or garage or office, or wherever you use your air conditioner, don't get cold. Or, you're constantly having to check the unit so it's operating more fully.

However, there are other ways you can tell if your air conditioner repair specialist needs to be called. Here are four odd signs you need air conditioner repair.

Your air conditioner is frozen over

If your air conditioner is frozen over, your first thought may be that your unit is working so well that it frosted over. After all, you want the air to be cold in your home, and a super cold air conditioner has to be working great. Right? Actually, an air conditioner that is frozen over is likely one that needs its filter changed or has other ventilation needs, and you need to turn the unit off and call your AC repair specialist as soon as you can.

Your air conditioner turns on a lot to keep your home cool

As long as your air conditioner is cooling your home, it doesn't matter how often it turns on, right? Nope. The air conditioner should be able to follow the advice from the thermostat that tells it when to kick on. If it's kicking on all the time, then you may need to have repairs done. Or at the very least, you should have your AC repair specialist check out the thermostat.

Your air conditioner smells sweet

Your air conditioner should not have any odor to it at all. It should only blow out the air it's passing through, and if it has an odor at all, or even if the odor is sweet and not irritating, you have to wonder what is going on. Your AC repair specialist can clue you in on whatever is causing your AC unit to act up. At any rate, it should not be smelling sweet or have any other scent, so speak to your AC repair specialist if your AC unit has a smell.

Your air conditioner is shaking but silent

You may think a noisy air conditioner is cause for concern, and you'd be right. However, a loud air conditioner isn't your only problem. If your air conditioner is silent but shaking a lot, then it may have a loose fan or be connected oddly. Turn the unit off and call your air conditioner repair specialist if this happens to you.
